How Fast Are the Databases Growing?
23andMe just released new information. We have recent, official updates for the database sizes of AncestryDNA and MyHeritage from RootsTech in early March. And while Family Tree DNA has never directly acknowledged the size of their autosomal database, several reports put it at about 1 million. That puts us in a great position to compare recent growth rates among the testing companies.
|Company||Time Period||Growth||Days in Period||Growth per Day||Relative Rate|
Across the four databases, nearly 43,000 new people are testing every single day. Wowzers!
We can also compare the relative growth rates of the companies. AncestryDNA continues to lead the pack with a database that’s growing more than twice as fast as 23andMe’s. 23andMe, in turn, is growing 7 times faster than MyHeritage which is growing twice as fast as Family Tree DNA.
I didn’t include GEDmatch in this comparison because they have been purging duplicate kits recently. As a result, their database appeared to grow much more slowly between January and March 2019 than in reality. In other words, the previous estimates were inflated by duplicates, which will be less of a problem moving forward. In the period prior to the purge (May 2019 to January 2019), they were averaging 805 new kits per day.
